Specicaton of Letters Patent.

Patented A110'. 9, 1910;

Application led April 14, 1910. Serial No. 555,374.

To all whom it may concern.'

Be it known that I, Pintor CURRALL PACE, a subject of Edward VII, King of Great Britain and Ireland, and residing at LOX- wood, Billinghurst, in the county of Sussex, England, have invented certain new and useful Improvements in and Relating to Apparatus for Generating Combustible Vapor, of which the following is a specification.

In apparatus for generating combustible vapor, gauzes have heretofore been employed for collecting foreign particles from the vapor. These gauzes become clogged and require to be cleaned thereby necessitating a certain amount of dismantling, reassembling, and readjustment of the appa.- ratus and consequent expenditure of time and trouble.

An object of this invention is to overcome this objection, and this I do by providing the generating tube with a solid core, preferably of metal, which will not co-rrode or shed particles and which is so fitted therein that, at the highest temperature which it reaches in use, the space between it and its containing tube is only just sufficient for the passage of the liquid and vapor along it. Thus, the liquid around the core in the generator, being in the form of a thin film, is immediately vaporized and the vapor passes from said space in the form of a steady stream. Moreover, as the said space is so small there is very little risk of solid particles passing along it and reaching the vapor passages. I prefer to make the core as thick as possible, consistent with its being able to quickly absorb heat, so that it shall have a large surface in order to reduce the risk of any appreciable blocking of the said space by solid particles. Further, in previously constructed apparatus of the type in question, it has not, so far as I am aware, been possible to supply vapor to a number of lights placed at a considerable distance from the generator so that they shall burn as smoothly and quietly as ordinary coalgas lights. According to the present invention, however, I do this by allowing the generator, carrying a core as above described, to extend beyond the direct vaporizing heat, and also by passing the vapor into a supply pipe which is provided with a vent.

Arranging the generator sothat it projects in the manner just described is probably not essential but it has the advantage quality.

of insuring a gradual heating of the petrol or the like, and I find that this arrangement of the generator combined with the vent, produces a smooth and quiet How of gas in the supply pipe. Moreover, I am enabled to use a comparatively large outlet orifice for the vapor at.the vapor-end of the generator, and I find that this enables me to obtain the correct mixture of vapor and air, and that the mixture can be conducted through long distances without condensation, and without any deterioration in The preferred method of carrying out this invention is illustrated in the accompanying drawings, wherein- Figurel is an elevation, partly in section, of my improved apparatus, and Fig. 2 is an elevation showing said apparatus covered by a heat-retaining cover. Fig. 3 shows diagrammatically the application of this invention to lighting and cooking apparatus. Fig. 4L is an elevation, partly in section, of an arrangement of generators arranged one above the other according to this invention. Fig. 5 is a plan, partly in section, and shows a single generator combined with a plurality of vapor outlet nipples in accordance with this invention, and Fig. 6 is an elevation, partly in section, of a modification of my improved generator.

Like letters refer to like parts throughout the several views.

In the drawings, a is the core, which is composed of' material which will not corrode or shed particles, preferably brass or copper, and it is fitted slidingly within a tube Y). The space between the core and the tube is shown exaggerated in the drawings for the sake of clearly showing it. The parts a and Zi comprise the generator.

c is a support which supports the generator (Figs. l, 2 and 3). At either end of the support c holes c', c are provided into which the generator is introduced, and in Fig. l the generator is held in position by means of screws d, d.

e is the petrol or the like supply-pipe which is secured to the generator by means of a nut f.

g is the vapor-exit nipple secured to the generator by means of a nut g. The vapor passes from the nipple g into the nipple 7b which is adjustably arranged in the vaporsupply pipe j. This pipe y' is furnished with a vent-pipe if; in which is placed a check valve 7c. Leading from the pipe is a bypass 5 which conducts a portion of the vapor to a pipe m; the supply of vapor thereto being regulated by a tap m2.

In Fig. l, the pipe x is held in place in the stand c by means of screws m, m. The vaporizing heat is obtained from jets ai* issuing from perforations in the pipe A portion only of the generator is in the direct heat-Zone of these jets, the remaining portion thereof being intended to carry the heat along and thereby effect a gradual vaporization of the petrol or `the like, resulting` in an even ejection of vapor from the nipple g. Variation of pressure in the vapor-supply pipe y' causes the check valve 7s to rise or fall, resulting in an even and quiet flow of vapor in said pipe and also at the burners. Each supply-pipe may supply a separate set of burners.

n, Figs. l, 2 and 3, is the heat-retaining cover, which is removable and is provided with inlet and exhaust openings x5 and m6. This cover is simply placed over the sta-nd c, where the latter is in the form shown in Fig. l, but the stand c* shown in Fig. 4l itself constitutes also the cover. As shown in this ligure the stand is provided with a number of generators a-Z) which pass through holes 010 in the stand and are held in place by nuts fx and gx. The burner in this ligure is held in place by the tap m2 and a back nut In this figure each generator is connected with the vent pipe le* by means of a connection k2 in which connection the check valve is located. The vent pipe is supported by an arm c2 and aA screw c passing through the outer end of said arm. The covei` c* is provided with an air inlet 'w5 and an eX- haust m61.

An example of how the apparatus may be used in connection with ordinary lighting and cooking apparatus is shown in Fig. 3, in which 0, p represent two rooms of a dwelling house. The generating apparatus may be placed in a fire-place g, or it may even be placed outside the house, so as to reduce the risk of fire. The vapor is conducted by means of pipes 7^ to an ordinary coal-gas cooking-stove s in the room o, and to ordinary eoal-gas lighting-burners t in the room p.

Referring to Fig. 5, u, u are branches connected with a single generator, and the v'a= por-outlet nipples g, g of these branches may be of dierent sizes so as to deliver different quantities of vapor into the supplypipes j, j (each of which may be connected to a separate set of burners) depending upon the number of burners it is desired to supply from each pipe.

In the modilied form of generator shown in Fig. (5, the core a is first placed within the tube b, and the two are then bent together. This forni of apparatus is useful when it is desired to combine the generator with a gas-fitting such as a wall-bracket or chandelier. In the ligure the generator is supported by a pipe v which forms part of a wall-bracket and carries a double T-joint o, the lower portion of which supports the vapor-supply pipe, part of which is shown at j. This pipe is intended to carry an ordinary burner, the globe of which is indicated at w. A receptacle a; is arrai'lged beneath the generator and is adapted to contain spirit for the usual preliminary heating of the generator, the heat of which is subsequently maintained by heat from the burner. The supply of petrol or the like to the generator is controlled by a tap y.

I claim An apparatus for generating combustible vapors comprising a stand, a tube supported therein, a non-corrosive core in the tube leaving a film-space between itself and the tube, a supply pipe connected with one end of said space, an exit nipple connected with the other end, a vapor supply pipe, an adjustable nozzle therein located oppositie the exit nipple and spaced therefrom for receiving the vapor from said nipple, a vent pipe connected with said vapor supply pipe, a check valve therein for compensating the variations of pressure of the fluid, a burner in said stand below the tube and a by-pass pipe leading from said vapor supply pipe to the burner, said tube and core extending beyond the direct heat zone of the burner.

In witness whereof I have hereunto set my hand in the presence of two witnesses.
